It is the drop that does it, not the level.

THE PATTERN THAT TRACKS A CYCLE

Hormonal headache is triggered by the drop in estrogen late in the cycle, not by high or low levels. So attacks cluster from about two days before bleeding through the first two or three days of it. These menstrual attacks run longer and hit harder. They respond less to the usual abortive (attack-stopping drug).

Do your worst headaches land in the same two or three days every month? That is not a coincidence, and it is not something to put up with. Menstrual migraine acts differently from the rest, and it is treated differently.

What causes hormonal headaches?

Estrogen withdrawal is the trigger. It is the fall in the late luteal phase (the last days before a period), not high or low estrogen as such. That is why attacks cluster from about two days before bleeding starts through the first two or three days of it. It is also why the pattern is so predictable once someone is asked to look for it.

Predictable is the key word. That is because it is the only migraine trigger you can see coming on a calendar. That opens treatment options that do not exist for attacks you cannot predict.

Do hormonal headaches change with menopause or pregnancy?

Attacks often worsen in the years before menopause. Cycles turn erratic then, and estrogen swings widen. Many people then improve after menopause, once the swings stop. Pregnancy often improves migraine after the first trimester for the same reason. Levels stay stable and steady instead of cycling.

Why are some months worse than others?

The days before a period also bring poorer sleep and a less steady appetite. They often bring a heavier load of managing everything else, too. So the hormone drop lands on a week when two other thresholds are already lowered — sleep and steady blood sugar (glucose). That is why the same hormone fall gives a manageable day one month and a lost day the next. It is also why the plan targets all three, not the hormone alone.

Frequently asked questions

Why are my period headaches worse than my other ones?

Menstrual attacks are typically longer and more severe. They are more likely to come back after a first response. That is a recognized difference, not just an impression.

Will menopause fix it?

Often, in time. The years leading up to it are often worse, because the swings widen before they stop.

Is it safe to take the combined pill if I get migraines?

It depends on whether you have aura. With aura, combined hormonal contraception is generally avoided. Talk it through with your prescriber — and mention the aura by name, because it is the deciding detail.

What should I track?

Headache days against cycle days for two months. Two cycles make the pattern obvious. That pattern is what unlocks timed treatment — how to record it.

What does a hormonal headache feel like?

Usually like your other migraines, only worse. Menstrual attacks last longer and hit harder. They are more likely to come back after the first dose seems to work. They respond less to the usual abortive. And they often arrive without aura, even in people who get aura at other times of the month.

How do I know if my headaches are hormonal?

Look at the calendar. Hormonal attacks cluster from about two days before bleeding starts through the first two or three days of it. If your worst headaches land in that same window month after month, the pattern is hormonal. Log headache days against cycle days for two months. Two cycles make it obvious.

How do you get rid of hormonal headaches?

Use the one advantage this trigger gives you: it is predictable. Once two cycles of tracking show the pattern, treatment can be timed to arrive before the attack does. That is not possible with random headaches. The plan also targets the poorer sleep and unsteady blood sugar of the week before a period. That is because those lower the threshold the hormone drop lands on.
